Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot production technology, and more specifically, to an aluminum liquid filtration and purification device for aluminum ingot production. Background Technology

[0002] In the aluminum ingot production process, the filtration and purification of molten aluminum is a crucial step in ensuring the quality of the final product. Molten aluminum often contains non-metallic inclusions (such as oxides, flux residues, etc.), gases (such as hydrogen), and trace amounts of metallic impurities. These impurities can significantly reduce the mechanical properties, electrical conductivity, and corrosion resistance of aluminum ingots, affecting their application in high-end industrial fields.

[0003] In the prior art, such as the aluminum liquid filtration and purification device for aluminum ingot production disclosed in CN216325077U, the device includes a fixed frame, an inner connecting ring fixedly installed inside the fixed frame, and a filter barrel fixedly installed inside the inner connecting ring. However, the above-mentioned aluminum liquid filtration and purification devices often directly pour the aluminum liquid onto the filter screen, allowing the aluminum liquid to pass through the filter screen to filter impurities in the aluminum liquid. However, this easily leads to aluminum liquid splashing, and the filtration speed is slow. At the same time, it is not convenient to heat and maintain the temperature of the aluminum liquid, and it is difficult to avoid the aluminum liquid cooling and solidification, thus having certain defects in use.

[0010] Furthermore, the mesh size of the first filter screen is larger than that of the second filter screen.

[0011] Furthermore, a connecting pipe is installed inside the liquid outlet tank. The connecting pipe includes a connecting rod, a pipe body, and a base.

[0027] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0028] like Figures 1-3As shown in the figure, an aluminum liquid filtration and purification device for aluminum ingot production according to one embodiment of the present invention includes a filtration mechanism and a heating component. The filtration mechanism includes a tank body 1, a rotating structure 2 and multiple filter cylinders 3. The tank body 1 includes a filter tank 11 and a liquid outlet tank 12 connected vertically. The rotating structure 2 is installed inside the filter tank 11. Multiple filter cylinders 3 are respectively spaced on the rotating structure 2. The bottom of the rotating structure 2 has multiple liquid outlets communicating with the liquid outlet tank 12, and the liquid outlets correspond to the filter cylinders 3. The heating component includes a mounting shell 4 and a hot air blower 5. The mounting shell 4 is snapped onto the side wall of the filter tank 11 and extends into the interior of the filter tank 11. The hot air blower 5 is installed in the mounting shell 4 through a heat insulation plate 6, and a heat dissipation cavity is formed in the heat insulation plate 6.

[0029] The aforementioned aluminum liquid filtration and purification device for aluminum ingot production includes a rotating structure 2. The rotation of the rotating structure 2 inside the filter tank 11 drives multiple filter cylinders 3 to reciprocate, agitating the aluminum liquid and accelerating its flow rate within the filter tank 11, thus improving the filtration effect and efficiency. An outlet allows the aluminum liquid filtered from the filter cylinders 3 to flow into the outlet tank 12, completing the filtration and discharge of the aluminum liquid. A heating component heats the interior of the filter tank 11, keeping the aluminum liquid inside warm and preventing it from cooling and solidifying. A heat insulation plate 6 effectively dissipates the heat generated by the hot air blower 5 during operation, reducing its operating temperature and extending its service life.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, an inlet pipe 111 is connected to the side wall of the filter tank 11, and a flow monitoring module 112 is installed on the inlet pipe 111. The flow monitoring module 112 can accurately measure the flow rate of the aluminum liquid in the inlet pipe 111, avoiding excessive or insufficient feeding, meeting production needs while ensuring high efficiency and safety in the production process.

[0031] like Figures 1-3As shown, in one embodiment, the rotating structure 2 includes a rotating frame 21, a drive motor 22, and a rotating shaft 23. The rotating frame 21 is installed inside the filter tank 11, and the drive motor 22 is installed on the top of the filter tank 11. The output end of the drive motor 22 extends into the filter tank 11 and is connected to the rotating shaft 23 for transmission. The rotating shaft 23 is fixedly inserted into the rotating frame 21. Multiple filter screen cylinders 3 are spaced apart along the circumferential direction of the rotating frame 21, and the liquid outlet is opened at the bottom of the rotating frame 21. By providing the drive motor 22, the drive motor 22 controls the rotation of the rotating shaft 23, thereby controlling the rotational movement of the rotating frame 21 inside the filter tank 11, thus completing the agitation of the aluminum liquid. This effectively prevents the aluminum liquid from remaining stagnant, which could cause suspended solids, silt, and particulate matter in the aluminum liquid to not flow sufficiently, affecting the filtration effect and resulting in incomplete removal of impurities.

[0032] In one embodiment, the filter cylinder 3 is fitted with a first filter screen and a second filter screen detachably fitted onto the first filter screen, with a waste chamber formed between the first and second filter screens. Through the dual filtration of the molten aluminum by the first and second filter screens, impurities in the molten aluminum can be thoroughly filtered out, greatly improving the filtration effect of the filter cylinder 3.

[0033] Preferably, both the first and second filter screens are made of high-strength alkali-free glass fiber. High-strength alkali-free glass fiber has extremely high strength and excellent heat resistance, making the first and second filter screens stronger and less prone to breakage. At the same time, its excellent heat resistance prevents it from being melted by high-temperature molten aluminum, thereby greatly extending the service life of the first and second filter screens.

[0034] In one embodiment, the mesh size of the first filter is larger than that of the second filter.

[0035] like Figure 3 As shown, in one embodiment, a connecting pipe 7 is installed inside the liquid outlet tank 12. The connecting pipe 7 includes a connecting rod, a pipe body and a base. One end of the connecting rod is fixed to the top wall inside the liquid outlet tank 12, and the other end of the connecting rod is connected to the pipe body. The pipe body is supported on the base, and the base is threadedly fixed to the bottom wall inside the liquid outlet tank 12. A through-hole is provided on the base.

[0036] In one embodiment, a plurality of first liquid outlet pipes are connected at intervals on the pipe body, the number of first liquid outlet pipes being the same as the number of liquid outlets, and the two corresponding one-to-one. The first liquid outlet pipes are... Figure 3 It is not shown in the text.

[0037] like Figures 1-3As shown, in one embodiment, a second liquid outlet pipe 121 is provided at the bottom of the liquid outlet tank 12. One end of the second liquid outlet pipe 121 extends to the through-hole and communicates with the pipe body. The other end of the second liquid outlet pipe 121 is connected to a liquid distribution pipe 122, and a control valve is provided on the liquid distribution pipe 122.

[0038] like Figure 2 , Figure 4 and Figure 6 As shown, in one embodiment, multiple locking blocks 41 are spaced apart on the outer wall of the mounting shell 4. Each locking block 41 has a protruding locking portion that abuts against the side wall of the filter tank 11, and a threaded hole 411 is provided on the locking portion. One end face of the mounting shell 4 has an air inlet window 42 with a dustproof screen. The other end face of the mounting shell 4 extends into the filter tank 11 and has an air outlet 43. The air outlet direction of the hot air blower 5 faces the air outlet 43. Thus, by providing the locking blocks 41, the stability of the mounting shell 4 during installation is improved; by providing the dustproof screen, dust, particles, and other impurities are prevented from entering the filter tank 11, protecting the molten aluminum inside the filter tank 11 from contamination.

[0039] The hot air blower 5 mentioned above is existing technology, and its specific technical features and installation methods will not be described in detail here.

[0040] like Figure 5 As shown, in one embodiment, the heat insulation plate 6 includes a first positioning seat 61 and a second positioning seat 62 assembled on the first positioning seat 61. The first positioning seat 61 is threadedly installed in the mounting shell 4, and the second positioning seat 62 is threadedly connected to the air outlet 43. The heat dissipation cavity is formed between the first positioning seat 61 and the second positioning seat 62, and a plurality of heat dissipation holes 63 are provided on the side wall of the heat dissipation cavity.

[0041] like Figure 5 As shown, the first positioning seat 61 is provided with a plurality of first positioning holes 611; the second positioning seat 62 is provided with a plurality of second positioning holes 621.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
